Patented Apr. 7, 1936 UNITED STATES PATENT OFFICE Philip E. Young,Fairhaven, Mass, assignor to Acushnet Process Company, a corporation ofMassachusetts Application June 28,

2 Claims.

This invention relates generally to rubber containers for liquids, andparticularly to flexible rubber hot water bottles or bags.

Heretofore rubber hot water bottles have been so formed that in beingfilled, there was a tendency for persons to splatter hot water overtheir hands. This difficulty particularly exists in the ordinary form ofhot water bottle with a large body and a narrow neck, even though acollar is added around the filling hole, due tothe irregular escape ofair from the interior of the bottle as it is being filled, and also dueto the flexibility of the collar. Because of the nature and use of hotwater bottles, the filling hole and hard stopper cannot conveniently bemade larger, and splatters resulting from hasty filling are veryunpleasant. Therefore, in order to prevent splattering, I have devised ahot water bottle with the normal size body and filling hole, but withthe addition of an oval shaped funnel, integral with the bottle, whichfunnel at its top is provided with an incurved annular rim or lip ofrestricted diameter. Such an incurved lip intercepts splatters and anywater traveling upwardly and outwardly along the funnel portion has itsdirection changed to inwardly. As the water bubbles through the fillinghole there is little likelihood of resulting splatters passing theincurved annular rim of the funnel. Also the rim of restricted diameteracts as a stiffener and tends to prevent distortion of the funnel.Furthermore, by forming the funnel in an oval shape I so center thehanging or gripping flange that the downward pull of the weight of thebag and its contents cannot distort the funnel materially.

My invention will be made clear by reference to the accompanyingdrawing, which is for illustrative purposes only and are not to beunderstood as limiting the scope of my invention as the same may beemployed in various forms and embodiments.

In the drawing:

Fig. 1 is a perspective view of a hot water bottle embodying myinvention; Fig. 2 is a vertical section of the funnel and top portion ofthe bag; Fig. 3 is a vertical section taken at right angles to thesection of Fig. 2; and Fig. 4 is a section showing a'modification of theincurved rim or lip.

In these figures a hot water bag 6 is formed with an oval shaped inset 8through which a filling hole Ill runs, which latter may be threaded1934, Serial No. 732,749

as at I2 for the usual stopper. Above the oval inset 8 is an oval shapedfunnel member l4. At its top the funnel member may be molded of slightlythicker rubber if desired, and is formed with an incurved annular lip orrim l6 of restricted diameter. On one of the flatter sides of the ovalfunnel is provided a hanging or gripping flange 18, but as shown theincurved rim is preferably continued uninterruptedly across the face ofthe flange. Because of the oval shape of the funnel and inset, theflange may be centered almost over the center of gravity of the bag andcontents. Therefore in filling, the pull of the weight of the bag andcontents against the flange will not greatly distort the funnel or thecontinuous incurved rim.

As the water is Poured or pressure-fed into the funnel, the latter isnot distorted because it is stiffened by the annular lip l6, and retainsits shape. Splatters caused by the bubbling of air out of the bag, orotherwise, are in the main, intercepted by the incurved rim. Any suddenflow or swirl of water rising on the side of the funnel has itsdirection changed by the incurved rim or lip.

In Fig. 4 is shown an alternate form of means for diverting and changingthe direction of the flow of water ascending the side of the funnel, andfor intercepting splatters, comprising an inwardly and downwardly turnedlip 20. This form of lip turns back any water surging up the side of thefunnel.

While my invention has been described specifically in its application tohot water bottles, it may also be embodied in flexible containers forliquids generally and particularly douche bags, and the appended claimsinclude such embodiments.

What I claim is:

1. A hot water bottle comprising a flared, soft rubber mouth portion andan inwardly extending flange running round such mouth portion and madeintegral therewith, said flange extending inwardly a substantialdistance, whereby the mouth portion will be held substantially againstdistortion during filling.

2. A structure as specified in claim 1 which also includes an integralsupport member forming part of the mouth portion and extending upwardlytherefrom and in which the said flange extends across the base of suchsupport member.
